CS2714

error A check must be a bool, but this is got.

#What it means

A check (settings.validate, or the validate argument of an input) must be a bool condition: true when the settings are fine.

#Typical cause

• An input or a number passed on its own, as in settings.validate(len, ...).

#How to fix it

Write a comparison, such as len >= 2.

#Example

//@chartscript 1
indicator("Checked length")
const len = input.int(14, "Length")
settings.validate(len, "Length must be set")
plot(ta.sma(close, len))

Fixed

//@chartscript 1
indicator("Checked length")
const len = input.int(14, "Length")
settings.validate(len >= 2, "Length must be at least 2")
plot(ta.sma(close, len))
